To @ZZ who/1t t 11mg/ con/cern:

Be it known that 1, SAMUEL N. MCCLEAN, a citizen of the United States, residing at Y\`\Tashington, in the county of lVashington and State of Iowa, have invented new and useful Improvements in Firearms, of which the following is a specification.

My invention relates to improvements in firearms; and the objects of myimprovements are to provide an automatic rotating magazine for the reception, retention, and discharge of cartridges, their transfer therefrom to their proper position in the barrel of the firearm, and means for discharging the cartridge, extracting the shell, and continuously loading the barrel of the gun and discharging the cartridge by means of a sliding operg ating-handle located in the stoel; or handle of the firearm. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 represents a longitudinalsectional view of the barrel and magazine of the firearm and a view of the construction of the op erating device in the stool; or handle of the irearm with the left side of the stoel; or wall of the rearm removed, the left half ot' the operating-lever being also removed. Fig. 2 represents a cross-section of the firearm on the lines y y, the tubes of the magazine being empty, showing the walls of the stoel; A, the barrel B, the magazine C, the magazinetubes Q, and the end of the grooves M. Figs. 3 and 4 are front views of the cartridge-carrier, showing the vertical part of plate G and the diagonal groove in the same rotating the magazine and an end view of shells I I, Fig. 3 showing the shells open, Fig. et closed. Fig. 5 is a sectional view of the cartridge-carrier. Fig. G is a plan view of the operating sliding handle O,showing its twolateral walls and an inside view of t-he body of the handle, also the projection 13 and the pin 12 for attachment with the spring R,the pins elto control its motion, and the pin-openings 5 for attachment with locking-lever K. Fig. 7 represents the front wall of the chamber within the stock or handle of the firearm and is formed by the rear end of the barrel B and the plate 28, showing the opening 425, through which the cartridges pass from the magazine, also the slot 20 in which the projection l5 of the cartridge-carrier G moves. Fig. S is a horizontal sectional view of the stock or handle of the firearm on a line through the center of the bore of the barrel and breech-piece, showing the breech-piece with extraetors attached, the lugs 18, and the con verging grooves 41, in which the lugs 18 move and are guided. Fig. 10 is a longitudinal sectional view of the forward end of the magazine, showing its tubes, the plunger E, with its pin F, and the spring D, the slots 45, the catch-levers 32, and the spring 3i. Figs. U and ll representthe lockingspring 25 with projections for engaging and disengaging the cartridge-carrier as it rises and descends.

Similar letters and iigures refer to similar parts throughout.

In the drawings accompanying this specification I have illustrated the construction of my invention with reference to a repeating riie; but it will be apparent that the operating device will be generally applicable to breeeh-loading firearms.

The stock or handle of the firearm contains a chamber in which are located the various operating devices for transferring the cartridge from the magazine to the barrel of the iirearm, discharging the cartridge, extracting the shell, and rotating the magazine.

The operating sliding handle O is a long slide Usha-ped in cross-section, as shown in Figs. 1 and 6. Its body, as shown in the longitudinal section, Fig. l, is provided with a heel or projection 30, on which the operating force is exerted. This sliding operating-handle is U-shaped in cross-section, and its two sides rise up, and their exterior surfaces are adjusted to conform to the inner faces of the walls of the chamber in the stock or handle. It is constructed to slide back and forth in side of the chamber formed in the stock or handle of the firearm, the movements of this handle being controlled bythe pins 4, Figs. (5 and l. 'lhcse pins, located on the outer side of the lateral walls of the handle, are integrally attached to it and constructed to slide back and forth in the grooves 14, Fig.

l, said grooves being located in the opposite walls of the stock-chamber. The forward end of this sliding handle, Fig. G, is bifurcated and constructed to pass forward and upward on either side of the internal operat` IOO ing devices, as shown in Fig. 1. These separate ends are respectively hinged to the two locking-levers K.

The automatic action of the lookin g device is as follows: The locking-bar T, Fig. 1, is a broad strong bar pivotally hinged to the un der side of the breech-piece by pin 2l, Fig. 1. This bar is also pivotally joined on either side to the locking-levers K by pins 3G, Fig. 1. These pins 36 are integrally attached to the locking-bar, pass through circular openings in the levers K, and extend into grooves 7, Fig. 1. These grooves are turned upward toward their forward ends 'and are located in the walls of the chamber on its respective opposite sides, the grooves being identical in size, depth, and direction. The locking-levers K are pivotally hinged to the operatinghandle O by pins entering the holes 5, Fig. 1, the construction being such that when the operating-handle O is drawn back by the force of the hand operating on it the hinged connection of these levers at the opening 5, Fig. 1,-is opened, thereby removing the lower end of the lever K from beneath the rear end of the locking-bar T, allowing the pins 36, Fig. 1, to drop down out of the upward-turned forward part of the groove 7 ,Fig 1, and be drawn back through the rear part of said grooves, thereby causing the breech-piece and connected parts to be operated as required. The reverse action of the operating-handle O, caused by the resistance of the spring R, Fig. 1, drives the locking-pins 36, Fig. 1, forward through the rear part of the grooves 7, Fig. 1, when they are carried up into the forward part of the grooves 7, Fig. 1,l by the forward and upward motion of the locking-levers K, thereby locking the breech-piece in position in front of the bore of the barrel.

The breech-piece is a steel bar or bar, preferably square in transverse section and of a length and size to be determined by the size of the cartridge used in the particular firearm. Itis constructed to slide back and forth in the chamber formed by the walls of the stock or handle of the firearm, said chamber being on a line with the bore of the barrel. The breech-piece contains the usual tiring-pin, passing longitudinally through it. The under side of the breech-piece is recessed, so that the locking-bar T may be received therein and held in position by the locking-levers K, which are respectively pivotally attached thereto on the'opposite sides of T. In the center of the breech-piece at the forward end of the recess is located the lug 24, to which the locking-bar T is pivotally connected. There is provided in the under side of said breech-piece a chambered openin g 37, in which the end of the short arm of the lever J is introduced and by means of which the reciprocating motion of the breech-piece operates the lever J and reciprocates the cartridge-carrier. A pin 23 is preferably introduced laterally through the front of chamber 37 as a bearing for the end of lever J.

The rear end of the breech-piece, when in normal position, is in contact with the face of the hammer S, and its rearward movement forces the hammer backward into a cocked position. Grooves 43 may be cut in the sides of the breech-piece to enable the extractors to be compressed.

The automatic shell-extractors 17, which are illustrated in Fig. S, are attached to the opposite sides of the breech-piece at its forward end on a line with the central axis of the bore of the barrel. The extractors are provided with lugs or bearings 18, which slidein grooves in the opposite walls of the receiver. These grooves converge for some distance between their ends and toward their forward ends to such an extent that by having 'a compressing operation upon the bearings 18 they cause the catches of the extractors to seize upon the rim or flange of the cartridge asv it is entering the bore of the barrel, when the grooves'again become parallel and the extractors remain engaged with the shell after it has entered the bore. The extractors retain their grasp until by the rearward motion of thebreech-piece the shell is fully extracted. The gradual divergence in the grooves and the resultant diminishing of the pressure exerted on the bearings 18 cause the extractors to release the shell, when it either rolls outat the opening A or is thrown out at the top by the upward motion of the cartridge-carrier.

The foregoing-described construction differs from that shown and described in my previous application, Serial No. 384,9M, in forming the breech-piece to move on a line with the bore of the barrel. A new mode of operation is introduced by this construction and movement of the breech-piece which permits the extractor to be fixedly attached tothe breech-piece and to engage with the groove by a lu g or bearing, giving a more positive action to the extractor.

The automatic cartridge-carrier, Figs. 1, 3, et, and 5, consists in a steel plate having vertical and horizontal parts. The vertical plate, being somewhat broader than the horizontal plate, is constructed to move and slide in vertical grooves 35, formed in the opposite walls of the chamber in which the cartridge-carrier moves back and forth from the magazine to the bore of the barrel. On the front face of the vertical part of the plate G', Fig. l, (illustrated in Figs. 3, 4:, and 5,) is a diagonal groove 16, constructed to engage with the pin F and rotate the magazine. The horizontal part of the plate G (illustrated in Fig. 1) is of a width and length to be determined by the cartridge used in the particular weapon. It has on its under side a bearing 46, Fig. 1, for articulation with the forward end of the cartridgecarrier-lifting lever J Fastened to the central line of its upper surface are two semieircular shells I I, Figs. 3, et, and 5. They are constructed to slide smoothly one within the other, each shell having cut through its walls two diagonal parallel slots H, the slots in the IOC IIO

dierent shells converging from opposite directions to a common center, these slots being constructed to cross each other at a point immediately over the central longitudinal line of the horizontal plate G. Through the openings formed by the crossing of these slots pass the pins 3, Figs. l, 3, i, and 5, which pins retain the shells I I on the central line of the plate G and control the movements of these shells. The automatic action of the cartridgecarrier is as follows: XVhen a cartridge driven by the plunger E, Fig. l, and the force of the coiled spring D, Fig. l, passes out into the carrier-shells, it slides back through the shells until it comes in con tact with the end walls of the shells, and the cartridge forces the shells backward, and they at once by means of the diagonal slots H close upon the cartridge and hold it firmly in position, thereby causing the shells by sliding past the pins 3 in the diagonal grooves H to close around the cartridge from opposite directions, as illustrated in Fig. et, and they remain in that position until they are brought into the presence of the bore of the barrel. The forward motion of the breech-piece causing the shells to slide forward compels them to resume their former position. (Illustrated in Fig. The cartridge then being sufciently engaged in the bore of the barrel, the carrier G is dropped by the force of the spring 39, Fig. l, toits position in front of the magazine, when it immediately receives from the magazine another cartridge, as before. The cartridge-carrierliftingleverJ is actuated by the reverse movement of the breech-piece and the resilience of the spring 39. The short arm of this lever, coming in contact with the breech-piece, is drawn back by this breech-piece, thereby causing the long arm of this lever to carry the cartridge-carrier toits position in front of the bore of the barrel.

The automatically-rotating magazine, Fig. l, is held in position beneath the barrel by a pin 2, which passes into a central openin g in the magazine, and a removable pin l, Fig. l0, which passes through a removable arm into a corresponding central opening in the forward end of the magazine.

The magazine may be formed with two or more chambers. I have seen proper to illustrate it as possessing four chambers, as seen in the drawings. Each of these chambers Q., Figs. l and 2, is provided with a longitudinal groove M, Figs. l and 2. Within these chambers is located a plunger E, Fig. l, having a coiled spring D, Fig. l. integrally attached to the side of the plunger E is the pin F, constructed to slide back and forth in the groove M, Figs. l and 2. The force of the spring D, Fig. l, causes the plunger E to force from the upper chamber of the magazine the cartridges as they are required. When the last cartridge is ejected from the upper chamber of the magazine, the pin F, traveling in the groove M, projects from the end of the magazine and through the small opening 4S, Fig.

7, and engages with the diagonal groove 16, Figs. 3 and 4, by means of which engagement the upward motion of the cartridge-carrier causes the next loaded chamber of the niagazine to be rotated into position, its contents being then discharged, as hereinbefore described. The diagonal groove 1G in the face of the vertical plate G terminates at its lower part in a vertical groove, and the vertical groove shallows out and forms a projection l5, Figs. 3, 4, and 5. This projection extends out from the face of its plate and moves in the slot 20, Fig. 7, and when the carrier is forced upward this projection engages with the pin F and forces it and the plunger E back into the magazine, when the plunger is caught and held by the catch-lever 32 at the rear end of the magazine.

The catch-levers 32 at the rear end of the magazine and 32X at the forward end of the magazine are pivotally held in slots in the walls of the magazine, and their ends, provided with catches, are forced upward by the springs Si, pressing upon their other ends. They are forced out ot' engagement with the plunger by their rear or outward ends coming in contact with the rib uniting the barrel and the magazine. Theirconstruction and operation are similar tothe catch-lever devices shown in Fig. l0.

Then the chambers of the magazine are full of cartridges, the plungers are forced back and held, as shown by Fig. 10, by the catch-levers Fig. l0. These catch-levers are pivotally held at 33 in slots or openings in the walls of the cartridge-chambers, and their engagement with the plungers is effected by the springs 34. The rear ends of the catchlevers extend out of the wall of the magazine. When the magazine is rotated so as to bring one of the cartridge-chambers in front of the opening 43, Fig. '7, the outward ends of the catch-levers meet the under side of the rib between the barrel and the magazine and are depressed, and the lever is thus thrown out of engagement with the plunger,which is then forced by the spring D to expel the cartridge from the chamber.

The construction of my automatic firing device is as follows: The trigger N, Fig. 1,

ICO

IIO

pivotally attached to the projection a by the pin l0, Fig. l, is constructed to engage with the scar-notches 3l of the hammer S, Fig. l, its movements being' actuated by the spring 8, Fig. l. The automatic scar P, Fig. l, is joined by the pins 0 to the arm of the projection a, its forward end being forced against the notches 3l by the spring l0, its rear end being constructed to come in contact with the projection 2() of the operating-handle O, Figs. l and t3. This automatic trigger device affords a spring-actuated set for the hammer to engage and hold it in its cocked position and be released from the hammer by the handle in its forward movement, as hereinafter described. Thc automatic action of those triggers is as follows; Both of the triggers being y tomatic trigger P.

thrown against the scar-notches 3l of the hammer S when the handle O is drawn back by the force of the hand, the hammer also being drawn back by the rearward motion of the breech-piece, both triggers slip past and catch behind the notches 3l, thereby retaining the hammer in a cocked position until by the forward motion of the lever O the projections 20 of this lever coming in contact with the rear part of the automatic trigger P causes its forward end to become disengaged from the catches at a time when the cartridge has been driven into the bore of the barrel and the breech-piece locked in position, as hereinbefore described. The hammer being then only retained by the trigger N, the gun can be fired in the usual way by this trigger, but if rapid firing is desired the action of the automatic trigger can be utilized by drawing the trigger N fully back, so that the notch in the spring S will engage with the catch S on the trigger N, thereby leaving the action of the hammer to be controlled only by the automatic trigger, when the gun will be automatically discharged by the autom atie trigger, as hereinbefore described.

The projection d is rigidly attached to the bottom of the stock-chamber and has two upwardly-extending arms. These arms are bifurcated at their extremities, so as to receive and carry, respectively, the lever .I and the au- Itis also provided with a vertical chamber through which passes and is pivotally held the trigger N. In the opposite walls of the stock-chamber in line with the bore of the barrel and near the lower corners of the breech-piece are grooves, in each of which yis located and firmly attached at one end a `spring 25, provided with two latch-shaped catches 2G and 27. The front face of the spring is flush with the face of the wall. The groove behind the free end of the spring is deepened, so that it may be pushed back and the catches taken out of the way. Then the cartridge-carrier is elevated, it strikes the catch 27 and forces the spring in until the table of the carrier is above it, when the spring is restored and the catch 27 holds the table in position above it. It is released and the spring forced back by the forward movement of the breech-piece, which engages the catch 26 and frees the carrier to descend after it has left the cartridge.

It is evident that there may be many changes and modications in the construction of my invention and of its several parts without departing from the spirit of my invention, and I do not limit myself to the specific construction shown and described.l
